What are the factors affecting the air quality of the air shower?

Air shower is a versatile purification equipment widely used in medicine, food, bioengineering, etc. It is usually installed between clean room and non-clean room to blow away human body and carrying items entering the purification plant. Dust attached to the surface. At the same time, the air shower room also acts as an air lock to prevent unpurified air from entering the clean area. It is an effective device for personal purification and prevention of outdoor air pollution in the clean area.


In short, the air shower is the necessary passage into the clean room to reduce the pollution problems caused by entering and leaving the clean room. According to the working principle of the air shower, a large amount of dust particles brought in by people or objects are effectively and quickly removed after being filtered by a high-efficiency filter, and then filtered by the primary and high-efficiency filters and recycled to the air shower area. .


In order to achieve the effect of blowing, the air outlet of the air shower is designed to have a wind speed of more than 25 m/s and a wind speed of 18 m/s. Air shower room manufacturers basically provide modular assembly methods, and customers can assemble air shower sizes of various lengths according to actual needs.


At present, there are many types of air showers on the market, and there are many customers' choices. According to the industry, in addition to selecting the right equipment type, there are several factors that affect the air quality of the air shower:


Whether the operating rules are standardized


Workers in the clean room should work in strict accordance with the operating rules of the clean room. The doors and windows of the clean room should be closed at any time. The personnel and articles between the clean room and the non-clean room should have a buffer zone, and there should be wind bath equipment to prevent the convection of the airflow. Enter the clean room.


Air supply volume in clean room


The number of air changes in the clean room and the air supply volume of the air conditioning purification system are the main internal factors for maintaining the positive pressure and cleanliness of the clean room, but it is limited by the ultimate resistance of the filters in the purification system.


Clean maintenance cycle


The equipment in the clean room requires regular, regular, and fixed cleaning and maintenance. Whether the materials and cleaning liquid used in the cleaning meet the requirements of clean room management.


Source of pollution in production


For the user, the cleanliness of the clean room is the focus of their concern. The pollution source of the clean room in operation is the person and the items entering the clean room. The dust particles generated in the production are also another one that affects the cleanliness of the room. the reason.

Is management reasonable?


The reasonable diversion of people flow and logistics has important significance for maintaining the cleanliness of the room. Whether people dress and blow before entering the clean room, whether the dress meets the standards of clean management regulations, some people with special production requirements for cleanliness need to take bath before entering; whether the items are replaced before entering the clean room Packing and blowing, whether the replaced materials meet the clean room standards, etc.

Installation of jet dust removal equipment


According to the industry, most of the dust sources in the air shower are from the staff. When the workers enter the clean room or the clean room, it is difficult to completely remove the dust and dust attached to the workers. The insiders suggest that air-blasting equipment can be installed in the air shower room, which can remove the dust and bacteria attached to the staff and clothes to achieve the desired environmental cleanliness requirements.


With the improvement of GMP standards in the pharmaceutical industry and the stricter management of pharmaceutical production, the requirements for cleanrooms in the pharmaceutical and other industries have further improved. Air shower room R&D manufacturers are striving to explore new technologies to further improve the overall cleanliness standards of the equipment and promote the development of the industry.
